CRUD with the PHP language and ORACLE DB

If you do not use a framework to make a software, maybe you have a confusion about how to start or the best option to develop.

In this case, we construct software for creating, read, update and delete data referent to a consulting room dentist, easy, fast, and with little dependencies, perfect for a place without internet or in critic moment that we will have developed

This CRUD software did are developed with:

PHP
Javascript
HTML
CSS
jQuery
Oracle (Yes Oracle is not necessarily more fast DB for develop, but in this case, the investigation is required because we did learn about this in the university)

How work?

Run sql scripts with oracle db in the order:
1. db-files/CentroOdontologico.sql
2. db-files/datos.sql
Server de index.php in app-files/

Have many things the software? (only about data base)

(all sql scripts are in db-files/CentroOdontologico.sql)
